To all'w'wm it may concer/n.'

Be 1t known that I, ALWIN VON Auw,

York, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Gumming or Molstening Labels or the Like, of which the following 1s a specification.

This invention relates to machines for gumming or inoistening labels or the like, and the principal object of the invention is to provide a simple, compact and inexpensive machine for the purpose mentioned in which the roller commonlyemployed for producing counter-pressure on the labels or other slips of material upon which the machine operates .is done away with and all possibility of moistenin or gumming the top surface of the labels thereby obvia-ted.

Other objects of the invention will appear as the same is more fully disclosed.

One embodiment of the invention is hereinafter described in detail, reference being had to the accompanying drawings, in which corresponding parts are designated bysimilar characters of reference, and the scope of the invention is clearly set forth in the appended claims.

In the. drawings: Figure l is a plan view of the machine, a portion of the shield or cover over the applying roller being removed to show the upper surface of the roller. lfig. 2 isa view in longitudinal vertical section tlirough the complete machine.

Referring to the drawings by the reference characters marked thereon, QB designates a bed plate upon which the machine is prefer ably mounted, and l denotes the su )porting frame of the machine, which is preferably a metal casting, but which may be constructed in any suitable manner. ln the sides of the frame 1 open bearings are formed to receive the spindle or shaft 2 of a relatively large, liquid applying roller 3, which is )refers-bly made hollow in order to reduce t ie weight thereof and which is also provided on its cylindrical surface with a. plurality of circumferential grooves hl, the purpose of which will hereinafter appear. 'lhe liquid applying roller 3 is rotated in its bearings by means of a small crai'ilc mounted upon the shaft. or spindle 2, and the lower portion of the roller lies in the liquid L which is contained in a tray 'l of any suitable material which is supported upon the bed B of the machine bea ,l neath the liquid applying roller, as best seen c1t1zen ofthe United States, residing in New in F ig. 2. The tray T is preferably removable from the bed and is kept in position upon the bed by cleats l) secured u on the bed to deiinc the proper position of t 1e tray.

The labels or other slips of material to be gummed or moistencd by the machine are introduced thereinto from a feed table or feed plate 6, which is rigidly mounted at the front end of thc frame l and is preferably set in a plane substantially normal to the adjacent portion of the surface of the liquid applying roller in order to insure complete contact of the slips with the roller. vSlightly above t-he feed table or plate 6 and adjacent to the liquid applying roller, a guide roller 7 is supported in open bearings formed in the sides of the frame l, and this guide roller 7 insures proper contact of cach label or other slip of material with the liquid applying roller as it passes into the machine. In order to keep the labels or other slips in proper contact wit h the liquid applying roller after passing under the guide roller 7 and also to pre vent the lodgment of dust or other foreign particles upon the surface of the liquid applying roller, a shield or cover 8 is provided over the liquid applying roller. This shield or cover corresponds approxinnrtcly to the contour of the roller and is preferably provided with pivots t) at one margin which turn in open bearings formed in bosses upon the sides of the frame l. The 'shield or cover isylield in proper relation to the liquid applyingfroller when the machine is in operation by 'a pair of pivoted catches l0 provided on the ends of the shield or cover and adapted for engagement with the axis or spindle of the li uid applying roller.

7hen the machine is in operation, the liquid applying? roller is turned by means of the crank 5, and the labels or other slips of material fed to the roller by being passed over the. 'feed plate or table and under the guide roller 7 are carried over with the liquid applying roller to which they adhere until they reach a point diametrically opposite the guide roller, where they are removed from the surface of the liquid applying roller by means of suitable stripping devices. These stripping devices consist preferably of a plurality of lingers 1l of thin metal, the stripping ends of which enter the grooves 4 formed in the cylindrical surface of the liquid. applying roller. These fingers :11 lie in parallel vertical planes and are mounted upon a cross bar 12 having at its ends trunnions which engage open bearings in the sides of the frame 1 of the machine. At their strip ping ends the fingers` 11 are slightly scooped out on their upper edges, as Shown at 13, in order' to facilitate the slipping of the edges of the labels or other slips of material over the fingers.

The action of the stripping fingers 1 1 in removing labels and other slips of material from the liquid applying roller is assisted by ashaft 14 provided at intervals With disks 15, fixed t-hereon and disposed parallel with the axis of the liquid applying roller in suitable open bearings formed therefor in the frame of the machine, the position of the shaft 14 being such that the edges of the disks l5 mounted on the shaftn'se a trifle higher than the upper edges of the stripping fingers 11, and the parts of the disks nearest the liquid applying roller barely escape contact therewith. The shaft 14 is rotated by means of a belt 16 preferably of resilient material, such as an endless coil spring, which runs over a suitable pulley 17 mounted at one end of the liquid applying roller and a smaller pulley 18 fixed upon the adjacent end of the shaft 1.4. A belt of resilient material is employed to Itransmit movement from the shaft of the liquid applying roller to the shaft 14 in order to permit the ready removal of the liquid applying roller and shaft from' the normal. position above the tray. The relative diameters of the pulleys 17 and 18 are such that the peripheral speed of the disks 15 is at least as great as the peripheral speed of the liquid applying roller when the machine is in operation. Consequently, as the labels or other slips of material are stripped from the sur' face of the liquid applying roller by means of the fin ers 11, they are engaged by the rotating dis s 15 on the shaft 14- and are carried toward the rear of the machine Where they may be conveniently removed from the stripping fingersand applied to parcels cr used in the sides of the frame 1 of the machine.

any other prferred manner.

As the thickness of the, coating of liquid upon the surface of the applying roller 3 must be uniform to insure good results, l

rovide a doctor or scraper 19 below the feed plate or table 6, and this doctorI or scraper i's preferably carried by a horizontal rod 20 vwhich is looselin bearings former l'iin e doctor or scraper resents a downwardly inclined blade2i wg with reference to the liquid applying roller by means of an adjusting screw 22 mounted in the frame 1 of the machine and .en aging an arm 23 of the doctor. When t e liquid to be appliedis highly fluid, the doctor need not be employed, but when a ich may be 'adjustedv erases thick or gummy liquid is to be applied, it is desirable to adjust the doctor carefully to insure a coating on the outer'surfacc of the liquid applying roller which is uniform in thickness and which will not cause the application of a surplus of liquid' tothe 'labels or o ther slips.

As will have been seen from the foregoing description, the entire machine is very simplein design, and the arts are so constructed and arran ed that they may be readily removed to acilitate the cleaningof 'the machine when necessary, or to permitthe curvature ofthe roller as they pass into the -machine and become moistened by the aste or other liquid carriedrupon the surace of the roller, if, however, a label should br s1 ifl'er than usual and not conform readily to the curvature of the liquid applying roller, the shield or cover over theA roller will'preventthe label from passing outof contact to the roller to any considerable eX- tent, and the guide roller 7.- will insure the contact of every portion ofthelabel with the liquid applying roller as it passes into the machine. While I have described indetail only a single embodiment of my invention, it Will be obvious that changes in the details'of construction and` in the proportions of thefparts may be made without departing fro'mfthe spirit of theinvention o'rsacrificin' the advantages thereof, and I do not, t erei'ore,l

limit myself to the precise form `of the invention described and shown, but reserve the right to make changes therein within the sco e ofthe ap ended claims.
